At the time of asking this question, doing bounty barely made money because market was in its downtrend. But at the time being, I would say doing bounty still brings you money, but much less than 2 or 3 years ago. Market shows some signs of bull run, projects (not only ICOs) want to attract cash flow and come up with bounty as a solution. If you're not good at trading and want to make money from cryptocurrency, bounty is a safe way.
